“…The detection of R. akari in Rhiphicephalus spp. in our study is therefore corroborating the earlier report of its being recovered from R. sanguineus collected from an infected dog in Mexico [30]. The capacity to adapt to new hosts and ecological environment is, therefore a huge epidemiological potential of this emerging human pathogen.…”

“…Although the PCR assay used should be specific for Rickettsia spp., the fragment amplified from R. sanguineus s. l. could not be sequenced. Other species of the Neotropical Region that can be found in R. sanguineus s. l. include R. massiliae, R. rhipicephali, "Candidatus R. amblyommii", R. akari, and R. felis (Zavala-Castro et al, 2009;Labruna et al, 2011;Parola et al, 2013).…”

The zoonotic transmission cycles of Rickettsia rickettsii and other spotted fever group (SFG) rickettsiae in Latin America have usually been associated with rural or sylvatic environments, although domestic dogs can be implicated in more populated settings. In this study, exposure of dogs to SFG rickettsiae in the Greater Metropolitan Area of Costa Rica was investigated. Dogs from sites associated with human cases and from dog shelters were evaluated by indirect immunofluorescence assay (IFA) using antigen of SFG rickettsiae. Rickettsia spp. were detected in ectoparasites by polymerase chain reaction (PCR). A total 18.5% (31/168) of dogs associated with human cases and 6.8% (11/161) of dogs in shelters had IgG end titers≥64 to Rickettsia spp. The odds of being seropositive were greater in dogs from areas associated with human cases when compared to shelters (OR: 3.2; 95% C.I: 1.5-5.6). Rhipicephalus sanguineus sensu lato (s. l.) was present in all sites associated with human cases. Rickettsia felis URRWXCal2 and R. felis-like RF2125 were detected in Ctenocephalides felis, and Rickettsia sp. IbR/CRC in Ixodes boliviensis. Results demonstrate that dogs from the main urban center of Costa Rica have been exposed to SFG rickettsiae, especially in areas with known human infection. Both human and animal health sectors must be aware of possible rickettsial diseases in urban areas, where dogs may also serve as sentinels for human infection.

“…La presencia de garrapatas positivas en perros domésticos infectados con Rickettsia spp. ya ha sido documentada en la región (14,35), por lo que estos ectoparásitos también representan un posible factor de riesgo para la transmisión Rickettsia spp. a otros animales domésticos, debido a su notable capacidad para parasitar numerosas especies de hospederos susceptibles, incluidos los seres humanos (26,36).…”

Introducción. Las bacterias del género Rickettsia son agentes causales de las rickettsiosis, enfermedades zoonóticas endémicas en México. En Yucatán, ocurrió un brote en habitantes de Bolmay; sin embargo, no se identificó el probable artrópodo transmisor. Objetivo. Reportar la presencia de Rickettsia spp. en garrapatas infestando perros domésticos de Bolmay.Material y métodos. Se trabajaron 105 viales con hasta ocho garrapatas. Se extrajo ADN de los ectoparásitos, posterior a la identificación del ciclo de desarrollo vital, la diferenciación sexual, género y especie. Se realizaron dos PCR para aislar fragmentos de los genes htrA (17-kDa) y rOmpB, pertenecientes a Rickettsia spp. Los productos positivos fueron secuenciados y analizados con la herramienta BLAST y el algoritmo Megablast. Resultados. Se utilizaron 291 garrapatas de los géneros Amblyomma (55.7%, 162/291), Rhipicephalus (34%, 99/291) e Ixodes (10.3%, 30/291), y las especies: Rhipicephalus sanguineus sensu lato, Ixodes affinis, Amblyomma cajennense y Amblyomma ovale. La positividad por PCR fue de 11.4% (12/105) para los géneros Amblyomma (66.7%, 8/12), Rhipicephalus (25%, 3/12) e Ixodes (8.3%, 1/12), y las especies A. cajennense, Rh. sanguineus s. l. e I. affinis. Se identificó ADN rickettsial en ninfas, larvas y adultos, y en machos y hembras. El análisis BLAST arrojó un 99% de cobertura e identidad con secuencias de Rickettsia spp.Conclusión. Los géneros y algunas especies de garrapatas infestando perros de Bolmay, probablemente están involucrados en el ciclo de transmisión de Rickettsia spp. a los habitantes. Se presenta la primera evidencia molecular de Rickettsia spp. en garrapatas I. affinis de Yucatán, México.
